Help using K2 template (changing font colors and adding sections)

I just became a user of WordPress today. I installed K2 and I am trying to modify it to my specifics. I have tried for the past 2 hours to change the color of certain fonts (I want to change the color of a)the title of the blog post; and b) the color of the links, both visited and roll over. I have tried, but to no avail.

Also, I want to know how I can add more sections to the top of my blog (ex. the ones I have now are “Blog” and “Archive”) I want to make more sections and have no idea how to do this. Can anyone help me in these areas? My site is: http://www.thetransformed.net
